Background Contemporary understanding of the biomechanics, natural history, and methods
of treating thoracolumbar spine injuries continues to evolve. Current classification schemes …

Objectives: The optimal surgical approach and treatment of unstable thoracolumbar spine
injuries are poorly defined owing to a lack of widely accepted level I clinical literature. This …

implants. Objectives. To review the biomechanics, design, and clinical data of currently …

Study Design. Prospective study of 5 spine surgeons rating 71 clinical cases of thoracolumbar
spinal injuries using the Thoracolumbar Injury Severity Score (TLISS) and then re-rating …

BACKGROUND CONTEXT: There are no published studies on the relationship between
total disc replacement (TDR) motion and the development of adjacent level degeneration (ALD)…

Study Design. Retrospective radiographic analysis. Objective. To retrospectively review a
group of patients undergoing anterior cervical discectomy and fusion (ACDF) to determine the …

BACKGROUND CONTEXT: Posterior ligamentous complex (PLC), consisting of supraspinous
ligament (SSL), interspinous ligament (ISL), ligamentum flavum (LF), and the facet joint …

surgery. Objectives. To examine incidence and types of neurophysiologic alerts and their …

Distinguishing between the normal gait of the elderly and pathologic gaits is often difficult.
Pathologic gaits with neurologic causes include frontal gait, spastic hemiparetic gait, …

BACKGROUND CONTEXT: The posterior ligamentous complex (PLC) is thought to contribute
significantly to the stability of thoracolumbar spine. Obvious translation or dislocation of an …
